LF sump and return pump

[daplatapus]

Hey all. I'm looking for a sump or tank I can turn into a sump for a basement fish room and a return pump that can push at least 1000 gph after 14' of head.
Really looking for a larger sump (48" minimum) but not too deep - say around 18" max. It's going in a dedicated fish room so would even think of deeper type type former frag tank. If you know of anything or have something around let me know with a pm.
Oh, and preferably on the island or the cost of a ferry ride kills me
Thanks!
